Hello.
I have a serious problem with the meter from 307 to NEC-u.
When I do go counter to soft counter ETL spill. Erased the memory and the counter has stopped working. I tried to read nec UPA and FF are the same. I tried to write it some input from my archive of NECA but not to count on. There is no indicator lights, none backlight timer nothing is dead. Are there any ways to fix the meter can anyone have the entire contents of FLASH and EEPROM NEC

NEC v 20 307 2.0 HDI

Thanks for this files, but my UPA USB (clone) don't read the chip.
error is: VSS/VDD error.
I think the Voltage is too up (10V)
I think it's a problem of UPA clone.
I have make same connection as Diga consult, same as DP3, same as UPA pdf in circuit and even tested on boad but same error.
Shittt!!!!
What is the problem???
Please help!!!!

The problem is on Datasheet NEC Upd780973 require +5V and when i connect my UPA i have error of "VSS/VDD OUT of range" and Voltmetre say me it's 9V inside pin 8 of MCU (IC VPP). I have tested by USB power and external power and same error.

What is the problem?
Maybe bad quality of UPA USB???

Please see your picture, you have shifted the pin 2,4,6,8. I'm talking about the picture, point near the lcd pins.
If you make your connection the pin 2 of adapter go to pin 77 of MCU.
